Burden of Disease

For the planning of health and care systems it is important to measure the so-called burden of disease within societies or related to specific diseases or social groups. A large-scale analysis of several longitudinal data bases of the populations 50 years of age and older shows that we have underestimated the burden of disease to societies of psychiatric disorders, like depression, in most societies.
A meta-study and overview of previous studies showed already that depression (age 60+) is more common in lower-income countries (between 25 and 33% of 60+population age group). High income countries, studied by Wang et al. 2024 in The Lancet Healthy Longevity, have rates of depression well below these levels, but a link to socioeconomic status, inactivity and loneliness is still evidenced. A five-year follow-up of persons aged 50+ years shows that the probability to develop a depression (hazard rate) is twice as high for persons with low socioeconomic status, who were socially
inactive and lonely than for socially active, high socioeconomic status and did not feel lonely at the beginning of measurement. The conclusion of the research highlights the need to develop and implement integrated and simultaneous initiatives to addressed the growing burden of disease related to depression in older persons.
